    # avoid having to use method missing in the future
    self.class.class_eval { def_delegator :@response, name }
    @response.send( name, *args, &block )

Instance Method Details

#finish ⇒ Object

Finish the response. This will send the response back to the client, so you shouldn’t attempt to further modify the response once this method is called. You don’t usually need to call it yourself, since it is called by the dispatcher once request processing is finished.

def rack_response; @response; end
